    Hydration, electrolytes

    Magnesium and all of the other minerals are still available in foods nonetheless; it is a requirement for their growth. Big ag has done a number on ruining both nutritional quality and soil health in the quest for greater production and profits, this is true. So don't support it! It is not the...

    Hydration, electrolytes

    With what is available to us year-round, dietary deficiencies are mostly a matter of personal choice these days.

    BDB with Vortex Cool?

    I used to use Vortex all the time. It makes a great climbing line. The BDB works on it but can be a bit stiff at times. I now use Samson Tangent as it has the same feel, almost, and is lighter.

    Anyone else give-up on routine "friction-saver" usage?

    LOL! @dspacio did a good job with the explanation. It is something that I do often. I thinking it has been years since I used a canopy anchor for a primary ascent. I am always searching for any way to stabilize the loading so that vectors are in compression and potential multipliers are...

    Anyone else give-up on routine "friction-saver" usage?

    There is so much more involved within these two setups than that. With careful thought and understanding, each situation can provide benefits worth doing.

    Tips and Tricks

    Are you compelled to make this the most contorted, incomprehensible, never-ending discussion on climbing systems? It's a climbing system! Stop bringing in groundies and magic.

    Tips and Tricks

    Burrapeg, your lost in your numbers and making assumptions based on your beliefs. If you would just setup all 3 systems and climb up a ways, you would see it is not magic, just a simple truth that when the climber is doing the pulling, the math changes.

    Tips and Tricks

    I do hope you actually realize that what we are discussing is nothing like a changing acronym. I am having trouble with your understanding of how much rope is used in each system, but still not accepting the face value of the numerical mechanical advantages. The amount of rope used per the...

    Tips and Tricks

    How the system works for the climber is the only accurate assessment of a climbing system. Calling it something else because it works differently in other applications is a 'yeah, but' and pointless argument.

    Tips and Tricks

    So, you chose the blue pill? You are fixated on the non-moving pulley while ignoring the fact that the distance from that pulley is moving closer to the one pulling, which makes it, in essence, a moving pulley. In a doubled rope system the climber pulls 2' of rope for every 1' foot of...

    Bowline slippage

    In the situation you describe, a bollard on either end would have been more likely to succeed without rope damage. This experience should not make you doubt a Bowline, just clarify where it can and cannot be used.

    Tips and Tricks

    Yes you are, but don't feel bad, I've known of some very knowledgeable people that still don't get it. The simplest way to verify this is to set up the 3 systems, a single line, a doubled line and the pictured haul-back system and haul yourself up each one.

    Tips and Tricks

    No. It is indeed a 3:1 because the puller is the load and is also moving. Many, many, people get that wrong.

    Root Failure When The Ground is Saturated with Rain

    Reading your past posts, your 'fears' are disproportionately higher than most tree workers. This is a job that has risks. So why pick it as an occupation?

    Root Failure When The Ground is Saturated with Rain

    This is an honest question and not me just being an ass, but with your ability to find so many things 'fearful', what made you think tree work was a good idea for you?

    Anyone able to recommend a full Haas Knee ascender setup ?

    I use the Haas Velox without the foot loop. It works great and I have no reservations, mechanically or ethically recommending it.

    Select and Check your anchor

    No. Much has changed in tree climbing in the last 50+ years. The trees, however, are not one of those. The other comment about 'old or bold' is an adapted saying from the world of pilots, and is just as untrue for them as it is for us. Bold does not mean reckless. Most pilots have nerves...

    Bigshot Sight/Finder

    With my APTA, I get approximately one foot of altitude per pound of tube pressure. Even though a calculated and gentle lob over a crotch is quite doable, I will rarely do so. Having a bit more air than needed, will create a more consistent shot and the small amount of excess power dissipates...

    Why do you like the thinner ropes?

    You have been teaching tree people for years, selflessly sharing your time and knowledge. You have earned the right to answer as you please. However, I hear this phrase frequently these days, regarding not doing your homework for you, and find it a bit of a perplexing response. You have real...
